ML_LFAST
ML_LFAST = [logical]
Default: ML_LFAST = .FALSE.
Description: This tag switches on the very fast execution mode for ML_ISTART=2.
Until now this tag is only available in the development version of VASP.
This tag significantly speeds up the calculation for ML_ISTART=2, but without the Bayesian error prediction.
One can still have Bayesian error prediction by carrying out the slow version every n steps, by setting
ML_IERR=n. But by default this is omitted.
